ET-900 (430-1000) Installation Faxback Doc. # 14109 Your telephone conforms to federal regulations, and you can connect it to most telephone lines. However, each device you connect to the phone line draws power from the phone line. We refer to this power draw as the device's ringer equivalence number, or REN. The REN is shown on the bottom of your phone. If you are using more than one phone or other devices on the line, add up all the RENs. If the total is more than five, your phone might not ring. In rural areas, a total REN of three might impair ringer operation. Note: You must not connect your phone to any of the following: Coin-operated systems Party-line systems Most electronic key phone systems Your telephone operates on standard radio frequencies, as allocated by the FCC. Even though the access protection code prevents unauthorized use of your phone line, it is possible for other radio units operating on similar frequencies within a certain area to unintentionally intercept your conversations and/or cause interference. This lack of privacy can occur with any cordless phone. Warning: To prevent fire or shock hazard, and damage to your telephone, do not expose it to rain or moisture. CAUTION: TO REDUCE TO RISK OF ELECTRONIC SHOCK, DO NOT REMOVE THE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. SELECTING A LOCATION You can place the base on a desk, shelf, or table, or mount it directly on the wall. Select a location which meets the following requirements: Near an AC outlet Near a telephone line jack Out of the way of normal activities Away from electrical machinery, electrical appliances, and metal walls or filing cabinets. Away from wireless intercoms, alarms, and room monitors. The base's location affects the phone's range. If you have a choice of several locations, try each location to see which one provides the best performance. If the phone line jack is not a modular jack, you must update the wiring. You can convert the wiring yourself, using jacks and adapters available at your local Radio Shack store. Or, you can let the phone company update the wiring for you. Note: The phone company will charge you for the installation of the necessary jacks. The phone company will ask you for the USOC number of the jack to be installed. This number is RJ11C for a baseboard jack. Direct wall mounting requires two screws not included with this phone. PHONE SETUP/MOUNTING You can set your ET-900 on a desk top or mount it directly on a wall. On a Desk Top 1. Plug one end of the supplied modular cord into the LINE jack on top of the base. 2. Plug the modular cord's other end into a modular phone line jack. 3. Insert the supplied AC adapter's barrel plug into the DC 9V jack on top of the base. 4. Plug the adapter into a standard AC outlet. DIRECTLY ON THE WALL Follow these steps to mount the base directly on the wall. This requires two screws (not supplied). 1. Drill two holes 3 15/16 inches apart. Then thread a screw into each hole, letting the heads extend 1/8 inch from the wall. 2. Plug one end of the supplied modular cord into the LINE jack on top of the base. 3. Plug the cord's other end into a modular phone line jack. 4. Insert the supplied AC adapter's barrel plug into the DC 9V jack on top of the base unit. Then plug the adapter into a standard AC outlet. 5. Align the keyhole slots with the mounting screws and slide the base downward to secure it. 6. Remove and turn the handset holder upside down so it holds the handset in place. USING THE TEL JACK You can connect an answering machine, dialer, or other phone to the TEL jack on top of the base. After you mount your phone, complete the following procedure before using it. CHARGING THE HANDSET'S BATTERY You must charge a new battery at least 12 hours before you use the phone. When you first charge the battery, set POWER ON/OFF on the handset to OFF. (When you recharge the battery you can leave POWER on, but the battery charges faster when POWER is OFF.) To charge or recharge the battery, simply place the handset on the cradle. The IN USE/CHG indicator lights. Full charging takes about 20 hours. Note: If the IN USE/CHG indicator does not light when you place the handset on the cradle, be sure the battery and AC adapter are correctly and securely connected. Also, check the charging contacts on the handset and base. If the contacts are dirty or tarnished, clean them with a pencil eraser. Recharge the battery when the LOW BATT indicator blinks. About once a month, fully discharge the battery. Otherwise, it loses its ability to recharge, and you have to recharge and replace it more often. To fully discharge the battery, keep the handset off the cradle until LOW BATT lights. Then return the handset to the base and fully recharge the battery. QUICK CHARGE You can use Quick Charge when charging the battery for the first time or when the low battery indicator lights. Press QUICK CHARGE while the handset is in the cradle. Quick Charge goes off automatically after about 6 hours so the battery doesn't overcharge. Caution: After using Quick Charge, so not press QUICK CHARGE again until the low battery indicator lights. Note: When the handset's battery will no longer charge, replace it. See "Replacing the Handset Battery." SETTING THE P/T (PULSE/TONE) SELECTOR Set P/T for the type of service you have (pulse or tone). If you are not sure which type you have, do this test. 1. Set P/T to T (Tone). 2. Set POWER ON/OFF on the handset to ON. 3. Press TALK on the handset and listen for a dial tone. 4. Press any number other than 0. If the dial tone stops, you have touchtone service. Leave P/T set to T. If it continues, you have pulse service. Set P/T to P. SETTING RINGER OFF/LO/HI RINGER OFF/LO/HI controls the base ringer's volume. The base does not ring when it is set to OFF. Notes: If the ringer is off when your receive a call, the IN USE/CHG indicator lights with each ring signal. If the handset is away from the base, it still rings even though the base's ringer is turned OFF. If the handset is on the base and the base ringer is off, the handset will not ring. (TK/all-03/13/95)
